2. Summary of Related Art

Improvements in the specificity of agents used to treat cancer is of considerable interest because of the therapeutic benefits which would be realized if the side effects associated with the administration of these agents could be reduced. Traditionally, dramatic improvements in the treatment of cancer are associated with identification of therapeutic agents acting through novel mechanisms.

Protein kinases are enzymes that catalyze the phosphorylation of proteins, in particular, hydroxy groups on tyrosine, serine and threonine residues of proteins. The consequences of this seemingly simple activity are staggering; cell differentiation and proliferation; i.e., virtually all aspects of cell life in one way or another depend on protein kinase activity. Furthermore, abnormal protein kinase activity has been related to a host of disorders, ranging from relatively non-life threatening diseases such as psoriasis to extremely virulent diseases such as glioblastoma (brain cancer).

Protein kinases can be categorized as receptor type or non-receptor type. Receptor-type tyrosine kinases have an extracellular, a transmembrane, and an intracellular portion, while non-receptor type tyrosine kinases are wholly intracellular.

Receptor-type tyrosine kinases are comprised of a large number of transmembrane receptors with diverse biological activity. In fact, about 20 different subfamilies of receptor-type tyrosine kinases have been identified. One tyrosine kinase subfamily, designated the HER subfamily, is comprised of EGFR (HER1), HER2, HER3, and HER4. Ligands of this subfamily of receptors identified so far include epithelial growth factor, TGF-alpha, amphiregulin, HB-EGF, betacellulin and heregulin. Another subfamily of these receptor-type tyrosine kinases is the insulin subfamily, which includes INS-R, IGF-IR, and IR-R. The PDGF subfamily includes the PDGF-alpha and beta-receptors, CSFIR, c-kit and FLK-II. Then there is the FLK family, which is comprised of the kinase insert domain receptor (KDR), fetal liver kinase-1 (FLK-1), fetal liver kinase-4 (FLK-4) and the fms-like tyrosine kinase-1 (flt-1). The PDGF and FLK families are usually considered together due to the similarities of the two groups. For a detailed discussion of the receptor-type tyrosine kinases, see Plowman et al., DN&P 7(6):334-339, 1994, which is hereby incorporated by reference.

The non-receptor type of tyrosine kinases is also comprised of numerous subfamilies, including Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack, and LIMK. Each of these subfamilies is further sub-divided into varying receptors. For example, the Src subfamily is one of the largest and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr, and Yrk. The Src subfamily of enzymes has been linked to oncogenesis. For a more detailed discussion of the non-receptor type of tyrosine kinases, see Bolen, Oncogene, 8:2025-2031 (1993), which is hereby incorporated by reference.

Since protein kinases and their ligands play critical roles in various cellular activities, deregulation of protein kinase enzymatic activity can lead to altered cellular properties, such as uncontrolled cell growth, associated with cancer. In addition to cancer altered kinase signaling is implicated in numerous other pathological diseases. These include, but not limited to: immunological disorders such as rheumatoid arthritis, graft-host diseases, multiple sclerosis, psoriasis; cardiovascular diseases such as artheroscrosis, myocardioinfarction, ischemia, stroke and restenosis; other inflammatory and degenerative diseases such as interbowel diseases, osteoarthritus, macular degeneration, diabetic retinopathy. Therefore, both receptor and non-receptor protein kinases are attractive targets for small molecule drug discovery.

One particularly attractive goal for therapeutic use of kinase modulation relates to oncological indications. For example, modulation of protein kinase activity for the treatment of cancer has been demonstrated successfully with the FDA approval of Gleevec® (imatinib mesylate, produced by Novartis Pharmaceutical Corporation of East Hanover, N.J.) for the treatment of Chronic Myeloid Leukemia (CML) and gastrointestinal stroma cancers. Gleevec is a selective Abl kinase inhibitor.

Attractive targets for modulation include VEGF receptor 2 (Flk-1/KDR), FGFR1, and PDGFR (alpha and beta). These three receptor tyrosine kinases have been implicated in blood vessel formation and proliferation (angiogenesis). Angiogenesis is associated with and required for the growth of malignant solid tumors, and has also been implicated in the development of diabetic retinopathy and rheumatoid arthritis, for example, (see: Cherrington J M, Strawn L M, and Shawver L K. New paradigms for the treatment of cancer: the role of anti-angiogenesis agents. Adv Cancer Res (2000)79:1-38; Ciulla T A, et al. Ocular perfusion abnormalities in diabetes. Acta Ophthalmol Scand (2002) 80:468-77; Walsh D A, Haywood L. Angiogenesis: a therapeutic target in arthritis. Curr Opin Investig Drugs (2001) 2:1054-63, all incorporated by reference herein for all purposes). Therefore, compounds and their formulations that modulate such receptors should be useful in the treatment of cancer, rheumatoid arthritis and visual impairment due to diabetic retinopathy, as well as the other indications as outlined in paragraph [0007] above.

Evidence for a direct role of VEGF and its receptor (Flk-1/KDR) in angiogenesis has been well-documented. It has been shown that disruption of VEGF signaling (with either anti-VEGF antibodies or soluble VEGF receptors) can inhibit neovascularization and compromise existing tumor vasculature, resulting in inhibition of tumor growth (see: Hanahan D. Signaling vascular morphogenesis and maintenance. Science (1997) 277:48-50; Holash J, et al. Vessel cooption, regression, and growth in tumors mediated by angiopoietins and VEGF. Science (1999) 284:1994-8; Gale N W, Yancopoulos G D. Growth factors acting via endothelial cell-specific receptor tyrosine kinases: VEGFs, angiopoietins, and ephrins in vascular development. Genes Dev (1999) 13:1055-66, all incorporated by reference herein for all purposes). Also, several inhibitors of the kinase activity of Flk-1/KDR have shown anti-tumor activity in rodents (see: Laird, A. D. Cancer Res (2000) 60:4152-60; Wood, J. M., Cancer Res (2000) 60:2178-89, both incorporated herein for all purposes).

Kinases, FGF and PDGF, also play important roles in angiogenesis, sometimes in concert with VEGF. Although FGF knockout mice have no apparent defects related to impaired angiogenesis, FGF2 is clearly an angiogenic factor in vivo (see: Klint P, Claesson-Welsh L., Signal transduction by fibroblast growth factor receptors. Front Biosci (1999) 4:D165-77, herein incorporated by reference for all purposes). Also, FGF can act synergistically with VEGF to induce the expression of VEGF. Kinases, PDGF and PDGFR, are expressed in microvascular endothelial cells during angiogenesis (see: Sato N, et al. Platelet-derived growth factor indirectly stimulates angiogenesis in vitro. Am J Pathol (1993) 142:1119-30; Lindahl P, et al. Pericyte loss and microaneurysm formation in PDGF-B-deficient mice. Science (1997) 277:242-5, both incorporated by reference herein for all purposes). Like FGF, PDGF stimulates angiogenesis by up-regulating VEGF production. PDGF also stimulates the proliferation of pericytes and fibroblast-like cells surrounding endothelium. FGF and PDGF are also tumor cell mitogens, and their receptors are expressed in a variety of human cancers (see: Singh R K, et al. Cell density-dependent regulation of basic fibroblast growth factor expression in human renal cell carcinoma cells. Cell Growth Differ (1996) 7:397-404; Hermanson M, et al. Platelet-derived growth factor and its receptors in human glioma tissue: expression of messenger RNA and protein suggests the presence of autocrine and paracrine loops. Cancer Res (1992) 52:3213-9, both incorporated by reference herein for all purposes).

Accordingly, the identification of small-molecule compounds that specifically inhibit, regulate and/or modulate the signal transduction of kinases, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, and PDGFR (alpha and beta), is desirable as a means to treat or prevent disease states associated with abnormal cell proliferation and is an object of this invention.

DETAILED DESCRIPTION OF THE INVENTION

The compositions of the invention are used to treat diseases associated with abnormal and or unregulated cellular activities, in particular those related to kinase activity, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, and PDGFR (alpha and beta).

DEFINITIONS

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.

The symbol “—” means a single bond, “═” means a double bond, “≡” means a triple bond. The symbol

refers to a group on a double-bond as occupying either position on the terminus of a double bond to which the symbol is attached; that is, the geometry, E- or Z-, of the double bond is ambiguous. When a group is depicted removed from its parent formula, the

symbol will be used at the end of the bond which was theoretically cleaved in order to separate the group from its parent structural formula.

If a group “R” is depicted as “floating” on a ring system, as for example in the formula:

then, unless otherwise defined, a substituent “R” may reside on any atom of the ring system, assuming replacement of a depicted, implied, or expressly defined hydrogen from one of the ring atoms, so long as a stable structure is formed.

If a group “R” is depicted as floating on a fused ring system, as for example in the formulae:

then, unless otherwise defined, a substituent “R” may reside on any atom of the fused ring system, assuming replacement of a depicted (for example the —NH— in the formula above), implied (for example as in the formula above, where the hydrogens are not shown but understood to be present), or expressly defined hydrogen (for example where in the formula above, “X” equals —CH—) from one of the ring atoms, so long as a stable structure is formed. In the example depicted, the “R” group may reside on either the 5-membered or the 6-membered ring of the fused ring system. In the formula depicted above, when y is 2 for example, then the two “R's” may reside on any two atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring.

When there are more than one such depicted “floating” groups, as for example in the formulae:

where there are two groups, namely, the “R” and the bond indicating attachment to a parent structure; then, unless otherwise defined, the “floating” groups may reside on any atoms of the ring system, again assuming each replaces a depicted, implied, or expressly defined hydrogen on the ring.

When a group “R” is depicted as existing on a ring system containing saturated carbons, as for example in the formula:

where, in this example, “y” can be more than one, assuming each replaces a currently depicted, implied, or expressly defined hydrogen on the ring; then, unless otherwise defined, where the resulting structure is stable, two “R's” may reside on the same carbon. A simple example is when R is a methyl group; there can exist a geminal dimethyl on a carbon of the depicted ring (an “annular” carbon). In another example, two R's on the same carbon, including that carbon, may form a ring, thus creating a spirocyclic ring (a “spirocyclyl” group) structure with the depicted ring as for example in the formula:

“Alkyl” is intended to include linear, branched, or cyclic hydrocarbon structures and combinations thereof, inclusively. For example, “C₈alkyl” may refer to an n-octyl, iso-octyl, cyclohexylethyl, and the like. Lower alkyl refers to alkyl groups of from one to six carbon atoms. Examples of lower alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, s-butyl, t-butyl, isobutyl, pentyl, hexyl and the like. Higher alkyl refers to alkyl groups containing more that eight carbon atoms. Exemplary alkyl groups are those of C₂₀ or below. Cycloalkyl is a subset of alkyl and includes cyclic hydrocarbon groups of from three to thirteen carbon atoms. Examples of cycloalkyl groups include c-propyl, c-butyl, c-pentyl, norbornyl, adamantyl and the like. In this application, alkyl refers to alkanyl, alkenyl, and alkynyl residues (and combinations thereof); it is intended to include cyclohexylmethyl, vinyl, allyl, isoprenyl, and the like. Thus when an alkyl residue having a specific number of carbons is named, all geometric isomers having that number of carbons are intended to be encompassed; thus, for example, either “butyl” or “C₄alkyl” is meant to include n-butyl, sec-butyl, isobutyl, t-butyl, isobutenyl and but-2-yne radicals; and for example, “propyl” or “C₃alkyl” each include n-propyl, propenyl, and isopropyl.

“Alkylene” refers to straight or branched chain divalent radical consisting solely of carbon and hydrogen atoms, containing no unsaturation and having from one to ten carbon atoms, for example, methylene, ethylene, propylene, n-butylene and the like. Alkylene is a subset of alkyl, referring to the same residues as alkyl, but having two points of attachment and, specifically, fully saturated. Examples of alkylene include ethylene (—CH₂CH₂—), propylene (—CH₂CH₂CH₂—), dimethylpropylene (—CH₂C(CH₃)₂CH₂—), and cyclohexylpropylene (—CH₂CH₂CH(C₆H₁₃)).

“Alkylidene” refers to a straight or branched chain unsaturated divalent radical consisting solely of carbon and hydrogen atoms, having from two to ten carbon atoms, for example, ethylidene, propylidene, n-butylidene, and the like. Alkylidene is a subset of alkyl, referring to the same residues as alkyl, but having two points of attachment and, specifically, double bond unsaturation. The unsaturation present includes at least one double bond.

“Alkylidyne” refers to a straight or branched chain unsaturated divalent radical consisting solely of carbon and hydrogen atoms having from two to ten carbon atoms, for example, propylid-2-ynyl, n-butylid-1-ynyl, and the like. Alkylidyne is a subset of alkyl, referring to the same residues as alkyl, but having two points of attachment and, specifically, triple bond unsaturation. The unsaturation present includes at least one triple bond.

Any of the above radicals, “alkylene,” “alkylidene” and “alkylidyne,” when optionally substituted, may contain alkyl substitution which itself contains unsaturation.

For example, 2-(2-phenylethynyl-but-3-enyl)-naphthalene (IUPAC name) contains an n-butylid-3-ynyl radical with a vinyl substituent at the 2-position of said radical.

“Alkoxy” or “alkoxyl” refers to the group —O-alkyl, for example including from one to eight carbon atoms of a straight, branched, cyclic configuration, unsaturated chains, and combinations thereof attached to the parent structure through an oxygen atom. Examples include methoxy, ethoxy, propoxy, isopropoxy, cyclopropyloxy, cyclohexyloxy and the like. Lower-alkoxy refers to groups containing one to six carbons.

“Substituted alkoxy” refers to the group —O-(substituted alkyl), the substitution on the alkyl group generally containing more than only carbon (as defined by alkoxy). One exemplary substituted alkoxy group is “polyalkoxy” or —O-optionally substituted alkylene-optionally substituted alkoxy, and includes groups such as —OCH₂CH₂OCH₃, and glycol ethers such as polyethyleneglycol and —O(CH₂CH₂O)_(x)CH₃, where x is an integer of between about two and about twenty, in another example, between about two and about ten, and in a further example between about two and about five. Another exemplary substituted alkoxy group is hydroxyalkoxy or —OCH₂(CH₂)_(y)OH, where y is for example an integer of between about one and about ten, in another example y is an integer of between about one and about four.

“Acyl” refers to groups of from one to ten carbon atoms of a straight, branched, cyclic configuration, saturated, unsaturated and aromatic and combinations thereof, attached to the parent structure through a carbonyl functionality. One or more carbons in the acyl residue may be replaced by nitrogen, oxygen or sulfur as long as the point of attachment to the parent remains at the carbonyl. Examples include acetyl, benzoyl, propionyl, isobutyryl, t-butoxycarbonyl, benzyloxycarbonyl and the like. Lower-acyl refers to groups containing one to six carbons.

“α-Amino Acids” refer to naturally occurring and commercially available amino acids and optical isomers thereof. Typical natural and commercially available α-amino acids are glycine, alanine, serine, homoserine, threonine, valine, norvaline, leucine, isoleucine, norleucine, aspartic acid, glutamic acid, lysine, omithine, histidine, arginine, cysteine, homocysteine, methionine, phenylalanine, homophenylalanine, phenylglycine, ortho-tyrosine, meta-tyrosine, para-tyrosine, tryptophan, glutamine, asparagine, proline and hydroxyproline. A “side chain of an α-amino acid” refers to the radical found on the α-carbon of an α-amino acid as defined above, for example, hydrogen (for glycine), methyl (for alanine), benzyl (for phenylalanine), and the like.

“Amino” refers to the group —NH₂. “Substituted amino,” refers to the group —N(H)R or —N(R)R where each R is independently selected from the group: optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heterocyclyl, acyl, carboxy, alkoxycarbonyl, sulfanyl, sulfinyl and sulfonyl, for example, diethylamino, methylsulfonylamino, furanyl-oxy-sulfonamino.

“Aryl” refers to aromatic six- to fourteen-membered carbocyclic ring, for example, benzene, naphthalene, indane, tetralin, fluorene and the like, univalent radicals. As univalent radicals, the aforementioned ring examples are named, phenyl, naphthyl, indanyl, tetralinyl, and fluorenyl.

“Arylene” generically refers to any aryl that has at least two groups attached thereto. For a more specific example, “phenylene” refers to a divalent phenyl ring radical. A phenylene, thus may have more than two groups attached, but is defined by the minimum of two groups attached thereto.

“Arylalkyl” refers to a residue in which an aryl moiety is attached to a parent structure via one of an alkylene, alkylidene, or alkylidyne radical. Examples include benzyl, phenethyl, phenylvinyl, phenylallyl and the like. Both the aryl, and the corresponding alkylene, alkylidene, or alkylidyne radical portion of an arylalkyl group may be optionally substituted. “Lower arylalkyl” refers to an arylalkyl where the “alkyl” portion of the group has one to six carbons; this can also be refered to as C₁₋₆ arylalkyl.

“Exo-alkenyl” refers to a double bond that emanates from an annular carbon, and is not within the ring system, for example the double bond depicted in the formula directly below.

In some examples, as appreciated by one of ordinary skill in the art, two adjacent groups on an aromatic system may be fused together to form a ring structure. The fused ring structure may contain heteroatoms and may be optionally substituted with one or more groups. It should additionally be noted that saturated carbons of such fused groups (i.e. saturated ring structures) can contain two substitution groups.

“Fused-polycyclic” or “fused ring system” refers to a polycyclic ring system that contains bridged or fused rings; that is, where two rings have more than one shared atom in their ring structures. In this application, fused-polycyclics and fused ring systems are not necessarily all aromatic ring systems. Typically, but not necessarily, fused-polycyclics share a vicinal set of atoms, for example naphthalene or 1,2,3,4-tetrahydro-naphthalene. A spiro ring system is not a fused-polycyclic by this definition, but fused polycyclic ring systems of the invention may themselves have spiro rings attached thereto via a single ring atom of the fused-polycyclic.

“Halogen” or “halo” refers to fluorine, chlorine, bromine or iodine. “Haloalkyl” and “haloaryl” refer generically to alkyl and aryl radicals that are substituted with one or more halogens, respectively. Thus, “dihaloaryl,” “dihaloalkyl,” “trihaloaryl” etc. refer to aryl and alkyl substituted with a plurality of halogens, but not necessarily a plurality of the same halogen; thus 4-chloro-3-fluorophenyl is within the scope of dihaloaryl.

“Heteroatom” refers to O, S, N, or P.

“Heterocyclyl” refers to a stable three- to fifteen-membered ring radical that consists of carbon atoms and from one to five heteroatoms selected from the group consisting of nitrogen, phosphorus, oxygen and sulfur. For purposes of this invention, the heterocyclyl radical may be a monocyclic, bicyclic or tricyclic ring system, which may include fused or bridged ring systems as well as spirocyclic systems; and the nitrogen, phosphorus, carbon or sulfur atoms in the heterocyclyl radical may be optionally oxidized to various oxidation states. In a specific example, the group —S(O)₀₋₂—, refers to —S— (sulfide), —S(O)— (sulfoxide), and —SO₂— (sulfone). For convenience, nitrogens, particularly but not exclusively, those defined as annular aromatic nitrogens, are meant to include their corresponding N-oxide form, although not explicitly defined as such in a particular example. Thus, for a compound of the invention having, for example, a pyridyl ring; the corresponding pyridyl-N-oxide is meant to be included as another compound of the invention. In addition, annular nitrogen atoms may be optionally quaternized; and the ring radical may be partially or fully saturated or aromatic. Examples of heterocyclyl radicals include, but are not limited to, azetidinyl, acridinyl, benzodioxolyl, benzodioxanyl, benzofuranyl, carbazoyl, cinnolinyl, dioxolanyl, indolizinyl, naphthyridinyl, perhydroazepinyl, phenazinyl, phenothiazinyl, phenoxazinyl, phthalazinyl, pteridinyl, purinyl, quinazolinyl, quinoxalinyl, quinolinyl, isoquinolinyl, tetrazoyl, tetrahydroisoquinolyl, piperidinyl, piperazinyl, 2-oxopiperazinyl, 2-oxopiperidinyl, 2-oxopyrrolidinyl, 2-oxoazepinyl, azepinyl, pyrrolyl, 4-piperidonyl, pyrrolidinyl, pyrazolyl, pyrazolidinyl, imidazolyl, imidazolinyl, imidazolidinyl, dihydropyridinyl, tetrahydropyridinyl, pyridinyl, pyrazinyl, pyrimidinyl, pyridazinyl, oxazolyl, oxazolinyl, oxazolidinyl, triazolyl, isoxazolyl, isoxazolidinyl, morpholinyl, thiazolyl, thiazolinyl, thiazolidinyl, isothiazolyl, quinuclidinyl, isothiazolidinyl, indolyl, isoindolyl, indolinyl, isoindolinyl, octahydroindolyl, octahydroisoindolyl, quinolyl, isoquinolyl, decahydroisoquinolyl, benzimidazolyl, thiadiazolyl, benzopyranyl, benzothiazolyl, benzoxazolyl, furyl, tetrahydrofuryl, tetrahydropyranyl, thienyl, benzothieliyl, thiamorpholinyl, thiamorpholinyl sulfoxide, thiamorpholinyl sulfone, dioxaphospholanyl, and oxadiazolyl.

“Heteroalicyclic” refers specifically to a non-aromatic heterocyclyl radical. A heteroalicyclic may contain unsaturation, but is not aromatic.

“Heteroaryl” refers specifically to an aromatic heterocyclyl radical.

“Heterocyclylalkyl” refers to a residue in which a heterocyclyl is attached to a parent structure via one of an alkylene, alkylidene, or alkylidyne radical. Examples include (4-methylpiperazin-1-yl) methyl, (morpholin-4-yl) methyl, (pyridine-4-yl) methyl, 2-(oxazolin-2-yl) ethyl, 4-(4-methylpiperazin-1-yl)-2-butenyl, and the like. Both the heterocyclyl, and the corresponding alkylene, alkylidene, or alkylidyne radical portion of a heterocyclylalkyl group may be optionally substituted. “Lower heterocyclylalkyl” refers to a heterocyclylalkyl where the “alkyl” portion of the group has one to six carbons. “Heteroalicyclylalkyl” refers specifically to a heterocyclylalkyl where the heterocyclyl portion of the group is non-aromatic; and “heteroarylalkyl” refers specifically to a heterocyclylalkyl where the heterocyclyl portion of the group is aromatic.

“Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. One of ordinary skill in the art would understand that, with respect to any molecule described as containing one or more optional substituents, that only sterically practical and/or synthetically feasible compounds are meant to be included. “Optionally substituted” refers to all subsequent modifiers in a term, for example in the term “optionally substituted arylC₁₋₈ alkyl,” optional substitution may occur on both the “C₁₋₈ alkyl” portion and the “aryl” portion of the molecule; and for example, optionally substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups, potentially ad infinitum. A list of exemplary optional substitution are listed below in the definition of “substituted.”

“Saturated bridged ring system” refers to a bicyclic or polycyclic ring system that is not aromatic. Such a system may contain isolated or conjugated unsaturation, but not aromatic or heteroaromatic rings in its core structure (but may have aromatic substitution thereon). For example, hexahydro-furo[3,2-b]furan, 2,3,3a,4,7,7a-hexahydro-1H-indene, 7-aza-bicyclo[2.2.1]heptane, and 1,2,3,4,4a,5,8,8a-octahydro-naphthalene are all included in the class “saturated bridged ring system.”

“Spirocyclyl” or “spirocyclic ring” refers to a ring originating from a particular annular carbon of another ring. For example, as depicted below, a ring atom of a saturated bridged ring system (rings B and B′), but not a bridgehead atom, can be a shared atom between the saturated bridged ring system and a spirocyclyl (ring A) attached thereto. A spirocyclyl can be carbocyclic or heteroalicyclic.

“Substituted” alkyl, aryl, and heterocyclyl, refer respectively to alkyl, aryl, and heterocyclyl, wherein one or more (for example up to about five, in another example, up to about three) hydrogen atoms are replaced by a substituent independently selected from: optionally substituted alkyl (for example, fluoromethyl), optionally substituted aryl (for example, 4-hydroxyphenyl), optionally substituted arylalkyl (for example, 1-phenyl-ethyl), optionally substituted heterocyclylalkyl (for example, 1-pyridin-3-yl-ethyl), optionally substituted heterocyclyl (for example, 5-chloro-pyridin-3-yl or 1-methyl-piperidin-4-yl), optionally substituted alkoxy, alkylenedioxy (for example methylenedioxy), optionally substituted amino (for example, alkylamino and dialkylamino), optionally substituted amidino, optionally substituted aryloxy (for example, phenoxy), optionally substituted arylalkyloxy (for example, benzyloxy), carboxy (—CO₂H), carboalkoxy (that is, acyloxy or —OC(═O)R), carboxyalkyl (that is, esters or —CO₂R), carboxamido, benzyloxycarbonylamino (CBZ-amino), cyano, acyl, halogen, hydroxy, nitro, sulfanyl, sulfinyl, sulfonyl, thiol, halogen, hydroxy, oxo, carbamyl, acylamino, and sulfonamido.

“Sulfanyl” refers to the groups: —S-(optionally substituted alkyl), —S-(optionally substituted aryl), and —S-(optionally substituted heterocyclyl).

“Sulfinyl” refers to the groups: —S(O)—H, —S(O)-(optionally substituted alkyl), —S(O)-optionally substituted aryl), and —S(O)-(optionally substituted heterocyclyl).

“Sulfonyl” refers to the groups: —S(O₂)—H, —S(O₂)-(optionally substituted alkyl), —S(O₂)-optionally substituted aryl), —S(O₂)-(optionally substituted heterocyclyl), —S(O₂)-(optionally substituted alkoxy), —S(O₂)-optionally substituted aryloxy), and —S(O₂)-(optionally substituted heterocyclyloxy).

“Yield” for each of the reactions described herein is expressed as a percentage of the theoretical yield.

Some of the compounds of the invention may have imino, amino, oxo or hydroxy substituents off aromatic heterocyclyl systems. For purposes of this disclosure, it is understood that such imino, amino, oxo or hydroxy substituents may exist in their corresponding tautomeric form, i.e., amino, imino, hydroxy or oxo, respectively.

Compounds of the invention are named according to systematic application of the nomenclature rules agreed upon by the International Union of Pure and Applied Chemistry (IUPAC), International Union of Biochemistry and Molecular Biology (IUBMB), and the Chemical Abstracts Service (CAS).

The compounds of the invention, or their pharmaceutically acceptable salts, may have asymmetric carbon atoms, oxidized sulfur atoms or quaternized nitrogen atoms in their structure.

The compounds of the invention and their pharmaceutically acceptable salts may exist as single stereoisomers, racemates, and as mixtures of enantiomers and diastereomers. The compounds may also exist as geometric isomers. All such single stereoisomers, racemates and mixtures thereof, and geometric isomers are intended to be within the scope of this invention.

It is assumed that when considering generic descriptions of compounds of the invention for the purpose of constructing a compound, such construction results in the creation of a stable structure. That is, one of ordinary skill in the art would recognize that there can theoretically be some constructs which would not normally be considered as stable compounds (that is, sterically practical and/or synthetically feasible, supra).

When a particular group with its bonding structure is denoted as being bonded to two partners; that is, a divalent radical, for example, —OCH₂—, then it is understood that either of the two partners may be bound to the particular group at one end, and the other partner is necessarily bound to the other end of the particular group, unless stated explicitly otherwise. Stated another way, divalent radicals are not to be construed as limited to the depicted orientation, for example “—OCH₂—” is meant to mean not only “—OCH₂—” as drawn, but also “—CH₂O—.”

Methods for the preparation and/or separation and isolation of single stereoisomers from racemic mixtures or non-racemic mixtures of stereoisomers are well known in the art. For example, optically active (R)— and (S)— isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. Enantiomers (R— and S-isomers) may be resolved by methods known to one of ordinary skill in the art, for example by: formation of diastereoisomeric salts or complexes which may be separated, for example, by crystallization; via formation of diastereoisomeric derivatives which may be separated, for example, by crystallization, selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic oxidation or reduction, followed by separation of the modified and unmodified enantiomers; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support, such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where a desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step may be required to liberate the desired enantiomeric form. Alternatively, specific enantiomer may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting on enantiomer to the other by asymmetric transformation. For a mixture of enantiomers, enriched in a particular enantiomer, the major component enantiomer may be further enriched (with concomitant loss in yield) by recrystallization.

“Patient” for the purposes of the present invention includes humans and other animals, particularly mammals, and other organisms. Thus the methods are applicable to both human therapy and veterinary applications. In a preferred embodiment the patient is a mammal, and in a most preferred embodiment the patient is human.

“Kinase-dependent diseases or conditions” refer to pathologic conditions that depend on the activity of one or more protein kinases. Kinases either directly or indirectly participate in the signal transduction pathways of a variety of cellular activities including proliferation, adhesion, migration, differentiation and invasion. Diseases associated with kinase activities include tumor growth, the pathologic neovascularization that supports solid tumor growth, and associated with other diseases where excessive local vascularization is involved such as ocular diseases (diabetic retinopathy, age-related macular degeneration, and the like) and inflammation (psoriasis, rheumatoid arthritis, and the like).

While not wishing to be bound to theory, phosphatases can also play a role in “kinase-dependent diseases or conditions” as cognates of kinases; that is, kinases phosphorylate and phosphatases dephosphorylate, for example protein substrates. Therefore compounds of the invention, while modulating kinase activity as described herein, may also modulate, either directly or indirectly, phosphatase activity. This additional modulation, if present, may be synergistic (or not) to activity of compounds of the invention toward a related or otherwise interdependent kinase or kinase family. In any case, as stated previously, the compounds of the invention are useful for treating diseases characterized in part by abnormal levels of cell proliferation (i.e. tumor growth), programmed cell death (apoptosis), cell migration and invasion and angiogenesis associated with tumor growth.

“Therapeutically effective amount” is an amount of a compound of the invention, that when administered to a patient, ameliorates a symptom of the disease. The amount of a compound of the invention which constitutes a “therapeutically effective amount” will vary depending on the compound, the disease state and its severity, the age of the patient to be treated, and the like. The therapeutically effective amount can be determined routinely by one of ordinary skill in the art having regard to his own knowledge and to this disclosure.

Thus, the term “cancerous cell” as provided herein, includes a cell afflicted by any one of the above-identified conditions.

“Pharmaceutically acceptable acid addition salt” refers to those salts that retain the biological effectiveness of the free bases and that are not biologically or otherwise undesirable, formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like, as well as organic acids such as acetic acid, trifluoroacetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid and the like.

Pharm. Sci., 1977;66:1-19 which is incorporated herein by reference.)

“Prodrug” refers to compounds that are transformed (typically rapidly) in vivo to yield the parent compound of the above formulae, for example, by hydrolysis in blood. Common examples include, but are not limited to, ester and amide forms of a compound having an active form bearing a carboxylic acid moiety. Examples of pharmaceutically acceptable esters of the compounds of this invention include, but are not limited to, alkyl esters (for example with between about one and about six carbons) wherein the alkyl group is a straight or branched chain. Acceptable esters also include cycloalkyl esters and arylalkyl esters such as, but not limited to benzyl.

Stella, “Pro-drugs as Novel Delivery Systems,” Vol 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference for all purposes.

“Metabolite” refers to the break-down or end product of a compound or its salt produced by metabolism or biotransformation in the animal or human body; for example, biotransformation to a more polar molecule such as by oxidation, reduction, or hydrolysis, or to a conjugate (see Goodman and Gilman, “The Pharmacological Basis of Therapeutics” 8.sup.th Ed., Pergamon Press, Gilman et al. (eds), 1990 for a discussion of biotransformation). As used herein, the metabolite of a compound of the invention or its salt may be the biologically active form of the compound in the body. In one example, a prodrug may be used such that the biologically active form, a metabolite, is released in vivo. In another example, a biologically active metabolite is discovered serendipitously, that is, no prodrug design per se was undertaken. An assay for activity of a metabolite of a compound of the present invention is known to one of skill in the art in light of the present disclosure.

In addition, the compounds of the present invention can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the present invention.

In addition, it is intended that the present invention cover compounds made either using standard organic synthetic techniques, including combinatorial chemistry or by biological methods, such as bacterial digestion, metabolism, enzymatic conversion, and the like.

“Treating” or “treatment” as used herein covers the treatment of a disease-state in a human, which disease-state is characterized by abnormal cellular proliferation, and invasion and includes at least one of: (i) preventing the disease-state from occurring in a human, in particular, when such human is predisposed to the disease-state but has not yet been diagnosed as having it; (ii) inhibiting the disease-state, i.e., arresting its development; and (iii) relieving the disease-state, i.e., causing regression of the disease-state. As is known in the art, adjustments for systemic versus localized delivery, age, body weight, general health, sex, diet, time of administration, drug interaction and the severity of the condition may be necessary, and will be ascertainable with routine experimentation by one of ordinary skill in the art.

Thus, administration can be, for example, orally, nasally, parenterally (intravenous, intramuscular, or subcutaneous), topically, transdermally, intravaginally, intravesically, intracistemally, or rectally, in the form of solid, semi-solid, lyophilized powder, or liquid dosage forms, such as for example, tablets, suppositories, pills, soft elastic and hard gelatin capsules, powders, solutions, suspensions, or aerosols, or the like, preferably in unit dosage forms suitable for simple administration of precise dosages.

The compositions will include a conventional pharmaceutical carrier or excipient and a compound of the invention as the/an active agent, and, in addition, may include other medicinal agents, pharmaceutical agents, carriers, adjuvants, etc. Compositions of the invention may be used in combination with anticancer or other agents that are generally administered to a patient being treated for cancer. Adjuvants include preserving, wetting, suspending, sweetening, flavoring, perfuming, emulsifying, and dispensing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

Solid dosage forms as described above can be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may contain pacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedded compositions that can be used are polymeric substances and waxes. The active compounds can also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. Such dosage forms are prepared, for example, by dissolving, dispersing, etc., a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, and optional pharmaceutical adjuvants in a carrier, such as, for example, water, saline, aqueous dextrose, glycerol, ethanol and the like; solubilizing agents and emulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propyleneglycol, 1,3-butyleneglycol, dimethylformamide; oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, castor oil and sesame oil, glycerol, tetrahydrofurfuryl alcohol, polyethyleneglycols and fatty acid esters of sorbitan; or mixtures of these substances, and the like, to thereby form a solution or suspension.

In one example, the composition will be between about 5% and about 75% by weight of a compound(s) of the invention, or a pharmaceutically acceptable salt thereof, with the rest being suitable pharmaceutical excipients.

Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see Remington's Pharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton, Pa., 1990). The composition to be administered will, in any event, contain a therapeutically effective amount of a compound of the invention, or a pharmaceutically acceptable salt thereof, for treatment of a disease-state in accordance with the teachings of this invention.

The compounds of the invention, or their pharmaceutically acceptable salts, are administered in a therapeutically effective amount which will vary depending upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of the compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular disease-states, and the host undergoing therapy. The compounds of the present invention can be administered to a patient at dosage levels in the range of about 0.1 to about 1,000 mg per day. For a normal human adult having a body weight of about 70 kilograms, a dosage in the range of about 0.01 to about 100 mg per kilogram of body weight per day is an example. The specific dosage used, however, can vary. For example, the dosage can depend on a number of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a particular patient is well known to one of ordinary skill in the art.

Utility of Compounds of the Invention as Screening Agents

To employ the compounds of the invention in a method of screening for candidate agents that bind to, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta), the protein is bound to a support, and a compound of the invention is added to the assay. Alternatively, the compound of the invention is bound to the support and the protein is added. Classes of candidate agents among which novel binding agents may be sought include specific antibodies, non-natural binding agents identified in screens of chemical libraries, peptide analogs, etc. Of particular interest are screening assays for candidate agents that have a low toxicity for human cells. A wide variety of assays may be used for this purpose, including labeled in vitro protein-protein binding assays, electrophoretic mobility shift assays, immunoassays for protein binding, functional assays (phosphorylation assays, etc.) and the like.

The determination of the binding of the candidate agent to, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta) protein, may be done in a number of ways. In one example, the candidate agent (the compound of the invention) is labeled, for example, with a fluorescent or radioactive moiety and binding determined directly. For example, thus may be done by attaching all or a portion of the target protein to a solid support, adding a labeled agent (for example a compound of the invention in which at least one atom has been replaced by a detectable isotope), washing off excess reagent, and determining whether the amount of the label is that present on the solid support. Various blocking and washing steps may be utilized as is known in the art.

By “labeled” herein is meant that the compound is either directly or indirectly labeled with a label which provides a detectable signal, e.g., radioisotope, fluorescent tag, enzyme, antibodies, particles such as magnetic particles, chemiluminescent tag, or specific binding molecules, etc. Specific binding molecules include pairs, such as biotin and streptavidin, digoxin and antidigoxin etc. For the specific binding members, the complementary member would normally be labeled with a molecule which provides for detection, in accordance with known procedures, as outlined above. The label can directly or indirectly provide a detectable signal.

In some embodiments, only one of the components is labeled. For example, the VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta) protein may be labeled at tyrosine positions using ¹²⁵I, or with fluorophores. Alternatively, more than one component may be labeled with different labels; using ¹²⁵I for the proteins, for example, and a fluorophor for the candidate agents.

The compounds of the invention may also be used as competitors to screen for additional drug candidates. “Candidate bioactive agent” or “drug candidate” or grammatical equivalents as used herein describe any molecule, e.g., protein, oligopeptide, small organic molecule, polysaccharide, polynucleotide, etc., to be tested for bioactivity. They may be capable of directly or indirectly altering the cellular proliferation phenotype or the expression of a cellular proliferation sequence, including both nucleic acid sequences and protein sequences. In other cases, alteration of cellular proliferation protein binding and/or activity is screened. In the case where protein binding or activity is screened, some embodiments exclude molecules already known to bind to that particular protein. Exemplary embodiments of assays described herein include candidate agents, which do not bind the target protein in its endogenous native state, termed herein as “exogenous” agents. In one example, exogenous agents further exclude antibodies to, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, and PDGFR (alpha and beta).

Candidate agents can encompass numerous chemical classes, though typically they are organic molecules having a molecular weight of more than about 100 and less than about 2,500 daltons. Candidate agents comprise functional groups necessary for structural interaction with proteins, particularly hydrogen bonding and lipophilic binding, and typically include at least an amine, carbonyl, hydroxyl, ether, or carboxyl group, for example at least two of the functional chemical groups. The candidate agents often comprise cyclical carbon or heterocyclic structures and/or aromatic or polyaromatic structures substituted with one or more of the above functional groups. Candidate agents are also found among biomolecules including peptides, saccharides, fatty acids, steroids, purines, pyrimidines, derivatives, structural analogs, or combinations thereof.

Candidate agents are obtained from a wide variety of sources including libraries of synthetic or natural compounds. For example, numerous means are available for random and directed synthesis of a wide variety of organic compounds and biomolecules, including expression of randomized oligonucleotides. Alternatively, libraries of natural compounds in the form of bacterial, fungal, plant and animal extracts are available or readily produced. Additionally, natural or synthetically produced libraries and compounds are readily modified through conventional chemical, physical and biochemical means. Known pharmacological agents may be subjected to directed or random chemical modifications, such as acylation, alkylation, esterification, amidification to produce structural analogs.

In one example, the binding of the candidate agent is determined through the use of competitive binding assays. In this example, the competitor is a binding moiety known to bind to, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta), such as an antibody, peptide, binding partner, ligand, etc. Under certain circumstances, there may be competitive binding as between the candidate agent and the binding moiety, with the binding moiety displacing the candidate agent.

In some embodiments, the candidate agent is labeled. Either the candidate agent, or the competitor, or both, is added first to, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta), for a time sufficient to allow binding, if present. Incubations may be performed at any temperature that facilitates optimal activity, typically between 4 and 40° C.

Incubation periods are selected for optimum activity, but may also be optimized to facilitate rapid high throughput screening. Typically between 0.1 and 1 hour will be sufficient. Excess reagent is generally removed or washed away. The second component is then added, and the presence or absence of the labeled component is followed, to indicate binding.

In one example, the competitor is added first, followed by the candidate agent. Displacement of the competitor is an indication the candidate agent is binding to, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta), and thus is capable of binding to, and potentially modulating, the activity of the target protein. In this embodiment, either component can be labeled. Thus, for example, if the competitor is labeled, the presence of label in the wash solution indicates displacement by the agent. Alternatively, if the candidate agent is labeled, the presence of the label on the support indicates displacement.

In an alternative embodiment, the candidate agent is added first, with incubation and washing, followed by the competitor. The absence of binding by the competitor may indicate the candidate agent is bound to the target protein with a higher affinity. Thus, if the candidate agent is labeled, the presence of the label on the support, coupled with a lack of competitor binding, may indicate the candidate agent is capable of binding to the target protein.

It may be of value to identify the binding site of, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta). This can be done in a variety of ways. In one embodiment, once the target protein has been identified as binding to the candidate agent, the target protein is fragmented or modified and the assays repeated to identify the necessary components for binding.

Modulation is tested by screening for candidate agents capable of modulating the activity of, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta), comprising the steps of combining a candidate agent with the target protein, as above, and determining an alteration in the biological activity of the target protein. Thus, in this embodiment, the candidate agent should both bind to (although this may not be necessary), and alter its biological or biochemical activity as defined herein. The methods include both in vitro screening methods and in vivo screening of cells for alterations in cell viability, morphology, and the like.

Alternatively, differential screening may be used to identify drug candidates that bind to the native target protein, but cannot bind to modified target protein.

Positive controls and negative controls may be used in the assays. For example, all control and test samples are performed in at least triplicate to obtain statistically significant results. Incubation of samples is for a time sufficient for the binding of the agent to the protein. Following incubation, samples are washed free of non-specifically bound material and the amount of bound, generally labeled agent determined. For example, where a radiolabel is employed, the samples may be counted in a scintillation counter to determine the amount of bound compound.

A variety of other reagents may be included in the screening assays. These include reagents like salts, neutral proteins, e.g., albumin, detergents, etc which may be used to facilitate optimal protein-protein binding and/or reduce non-specific or background interactions. Also reagents that otherwise improve the efficiency of the assay, such as protease inhibitors, nuclease inhibitors, anti-microbial agents, etc., may be used. The mixture of components may be added in any order that provides for the requisite binding.

Synthesis of Compounds

The following specific examples are provided as a guide to assist in the practice of the invention, and are not intended as a limitation on the scope of the invention. Using these examples as a guide, one skilled in art can synthesize compounds of the invention. Many starting materials and intermediates are commercially available. For example, there are many commercially available benzimidazole starting materials; and many benzimidazole syntheses, which use commercially available starting materials, are well known in the art.

Example 1 General Procedure for C-acylation of Benzimidazoles

To a 15 mL pressure tube was added benzimidazole (1 mmol) and a stirbar. Acetonitrile (4.7 mmol) was added. Triethylamine (2.9 mmol) was added followed by the appropriately substituted benzoyl chloride (2.9 mmol). Upon addition of the benzoyl chloride, the mixture became warm and viscous. The tube was sealed and heated at 135° C. for 2 hours while stirring. During heating, the mixture turned black in color. The tube was removed from the heat and its contents were diluted with acetone (approximately 3-4 mL per mmol of benzimidazole). The mixture was transferred to a round-bottomed flask containing 7% aqueous HCl (approximately 10-15 mL per mnuol of benzimidazole). Charcoal was added to the flask and the mixture was refluxed at 85° C. for 30 minutes. The mixture was allowed to cool and then was filtered through a Celite pad followed by a rinse with 1N HCl (25 mL). The filtrate was made alkaline with NH₄OH whereupon a solid precipitate formed. The solid was filtered, collected, and placed under high vacuum, yielding a solid ranging from white to brown, depending on the substituted benzoyl chloride used.

Example 2 General Procedure for the Condensation of Oxindoles with Substituted Benzoylbenzimidazoles

Procedure using ammonia: To a 15 mL pressure tube was added benzoylbenzimidazole (1 mmol), oxindole (1.05 mmol) and a stirbar. Anhydrous EtOH (approximately 5 mL per 1 mmol benzoylbenzimidazole) was added and the reaction vessel was cooled to 0° C. in an ice bath. NH₃ (g) was bubbled into the solution until saturation was achieved. The reaction vessel was sealed tightly and was heated at 90° C. overnight with stirring. After heating, the reaction mixture was dark and in some cases, a precipitate had formed. In cases where precipitation occurred, the bright yellow or orange crystals were filtered, collected, and confirmed to be the desired product. In cases where no precipitation was evident, the mixture was concentrated and purified via flash chromatography (15% to 50% EtOAc/Hex) to give bright yellow or orange crystals.

Procedure using unsym-dimethylethylenediamine: The procedure is the same as above with unsym-dimethylethylenediamine (5 mmol) used in lieu of NH₃ (g). Prior cooling to 0° C. is not necessary.

Example 3 2-chloro-N-(4-methoxyphenyl)-acetamide (an Oxindole Starting Material)

To a 500 ml round bottom flask was added p-anisidine (200 mmol), dichloromethane (100 ml) and triethylamine (250 mmol). The mixture was cooled to 0° C. and chloroacetyl chloride (220 mmol) in dichloromethane (20 ml) was added dropwise. The reaction was stirred at room temperature overnight. The reaction was concentrated and ethyl acetate was added to the solid. The solid was filtered off and the filtrate concentrated in vacuo to give product.

Example 4 5-hydroxyoxindole

2-chloro-N-(4-methoxyphenyl)-acetamide (10 g) and Anhydrous aluminum trichloride (17 g) was heated to 120° C. for 15 minutes and then heated to 240° C. for 1 hour. The reaction was cooled to room temperature and quenched with ice water and Concentrate hydrochloride acid, and extracted with ethyl acetate (5×). Organic layers combined and dried over magnesium sulfate, filtered and concentrated in vacuo. The crude solid was flash chromatography (silica, ethyl acetate) to give product.

Example 5 5-[1-(2-methoxyethyl)-piperdin-4-yloxy]-1,3-dihydro-indol-2-one

To an oven dried, nitrogen flushed 100 ml round bottom flask was added 5-hydroxyoxindole (10 mmol), 1-(2-methoxyethyl)-piperdin4-ol (11 mmol), triphenylphosphine (15 mmol), Anhydrous tetrahydrofuran (35 ml) and a stirrer bar. Diethyl azodicarboxylate (15 mmol) was added slowly to the mixture and stirred at room temperature overnight. The reaction was concentrated in vacuo and flash chromatography (silica, 5% methanol in ethyl acetate). Upon concentration a reddish oil (470 mg) was obtained with a 75% purity by H-NMR and LC/MS.

Example 6 General Procedure for the Reductive Amination of 5-amino-oxindoles with Ketones

To a 250 mL round bottom was added 5-amino-oxindole (2.61 mmol), dry 1,2 dichloroethane (80 mL), ketone (2.61 mmol), glacial acetic acid (1.35 mmol), and 4A molecular sieves. The reaction mixture was stirred at rt for 10 min. The reaction was then cooled to 0° C. in an ice bath before sodium triacetoxyborohydride (3.91 mmol) was added in one portion. The reaction was then warmed to rt and stirred overnight or until all starting materials are consumed. In cases where the reaction had not gone to completion, another 0.5 eq of sodium triacetoxy borohydride was added, and allowed to continue stirring at rt until the reaction was completed. The molecular sieves were removed via filtration and rinsed with a minimum amount of methanol. The filtrate was then basified with 5.0 mL of 2.0 M ammonia in Ethanol, concentrated via rotary evaporation, and purified by flash chromatography (typically with 90:10 CH₂Cl₂:MeOH) to give a brown oil. The oil was then lyophilized to give the product as a brown fluffy solid.

Alternatively, the reductive amination can be performed on the 5-amino-oxindole (5-amino-oxindole itself is commercially available from Combi-Blocs of San Diego Calif.) before condensation using the same procedure above. The solubility of polar starting materials may be aided with the addition of dry DMF (up to 25% v/v).

Also alternatively, the reduction amination can be carried out, for example, as follows:

5-(1-Ethyl-piperidin-4-ylamino)-1,3-dihydro-indol-2-one. To a 2 L round bottom flask was added 5-aminooxindole (80 g, 0.54 mol), 1,2-dichloroethane (800 ml), 1-ethyl-4-piperidone (80.1 ml, 0.59 mmol) and Glacial acetic acid (80 ml). The mixture was stirred for 30 minutes, cooled under ice/water bath for 30 minutes and then sodium triacetoxyborohydride (160 g, 0.76 mmol) was added in 10 portions over 60 minutes. The mixture was stirred at room temperature 4 hs. TLC showed no trace of amino-oxindole and then Celite (100 g) and MeOH (500 mL) were slowly added. The reaction mixture was filtered and concentrated. The resulting dark oil was acidified with c-HCl (150 mL) and ice (50 g). The reaction mixture was extracted with ethyl acetate (2 L×2) to remove the side product. The aqueous layer was cooled to 0° C., basified with 40% NaOH (ca. 150 mL) and then the solid was formed. After 30 min stirring, the formed solid was filtered and washed with H₂O (1 L) and suspended with Actone (2 L) for 1 h. After filtering, the crude solid was dissolved in CHCl₃ (2.5 L), treated with charcoal (50 g) and filtered using Celite. The filterate was concentrated and solidified with ethyl acetate to give the desired product (81 g, 58%).

The resulting dark red solution was agitated at room temperature for 16 hours before dumping into water (25 mL) and acidifying with 6M HCl (aq.) to pH about 3. The yellow/clear solution was extracted with ether (2×) washed with brine, dried over MgSO₄ and concentrated in vacuo. The yellow oil consisted of 2a and 2b at a ratio of 1.7:1 and ^(t)Butyl ethyl malonate (40 wt %) by ¹H NMR. The oil was purified by flash chromatography (silica, 15% Ethyl acetate in Hexanes). Upon concentration an orange oil (2.82 g) was obtained with an isomeric ratio 2a:2b of 2.4:1 and 37 wt % malonate. The yield, corrected for excess malonate, was 71.3%.

The mixture was stirred and transferred to a 2 L round-bottomed flask containing 7% aqueous HCl (1000 mL). Charcoal was added to the flask and the mixture was refluxed at 85° C. for 1 hour. The mixture was allowed to cool slightly and then was filtered through a Celite pad followed by a rinse with 1N HCl (˜200 mL). The filtrate was made alkaline with NH₄OH whereupon a solid precipitate formed. The solid was filtered and washed with copious amounts of dilute NH₄OH to remove triethylamine hydrochloride salts. The solid was collected and placed under high vacuum, yielding ketone 3 as an off-white solid (30.0 g, 80%).

(3Z)-5-[(1-ethylpiperidin-4yl)amino]-3-[(3-fluorophenyl)(4-methyl-1H-imidazol-2-yl)methylidene]-1,3-dihydro-2H-indol-2-one To a 350 mL pressure vessel was added 5-(1-ethyl-piperidin-4ylamino)-1,3-dihydro-indol-2-one (2) (10.00 g, 38.5 mmol, 1.0 eq.) and a stirbar. Anhydrous EtOH (90 mL) was added followed by acetic acid (2 mL, 34.7 mmol, 0.9 eq.) and the mixture was stirred at room temperature for 20 min. Upon achieving a homogeneous solution, 2-(3-fluorobenzoyl)-4-methylimidazole (3) (8.66 g, 42.4 mmol, 1.1 eq.) was added and the reaction vessel was cooled to 0° C. in an ice bath. NH₃ (g) was bubbled into the solution until saturation was achieved. The reaction vessel was sealed tightly and heated at 100° C. overnight with stirring. Soon after heating, the reaction mixture became dark in color. The reaction mixture was removed from heat, cooled to room temperature and concentrated. The crude was purified via flash chromatography (3%-15% MeOH/CH₂Cl₂ gradient) to give (3Z)-5-[(1-ethylpiperidin-4-yl)amino]-3-[(3-fluorophenyl) (4-methyl-1H-imidazol-2-yl)methylidene]-1,3-dihydro-2H-indol-2-one as a dark purple solid (13.5 g, 79%).

Assays

Kinase assays were performed by measurement of incorporation of γ-³³P ATP into immobilized myelin basic protein (MBP). High binding white 384 well plates (Greiner) were coated with MBP (Sigma #M-1891) by incubation of 60 ul/well of 20 μg/ml MBP in Tris-buffered saline (TBS; 50 mM Tris pH 8.0, 138 mM NaCl, 2.7 mM KCl) for 24 hours at 4° C. Plates were washed 3× with 100 μl TBS. Kinase reactions were carried out in a total volume of 34 μl in kinase buffer (5 mM Hepes pH 7.6, 15 mM NaCl, 0.01% bovine gamma globulin (Sigma #I-5506), 10 mM MgCl₂, 1 mM DTT, 0.02% TritonX-100). Compound dilutions were performed in DMSO and added to assay wells to a final DMSO concentration of 1%. Each data point was measured in duplicate, and at least two duplicate assays were performed for each individual compound determination. Enzyme was added to final concentrations of 10 nM or 20 nM, for example. A mixture of unlabeled ATP and γ-³³P ATP was added to start the reaction (2×10⁶ cpm of γ-³³P ATP per well (3000 Ci/mmole) and either 10 μM or 30 μM unlabeled ATP, typically. The reactions were carried out for 1 hour at room temperature with shaking. Plates were washed 7× with TBS, followed by the addition of 50 μl/well scintillation fluid (Wallac). Plates were read using a Wallac Trilux counter. This is only one format of such assays, various other formats are possible, as known to one of ordinary skill in the art.

One measure of inhibition is K_(i). For compounds with IC₅₀'s less than 1 μM, the K_(i) or K_(d) is defined as the dissociation rate constant for the interaction of the agent with, for example VEGF receptor 2 (Flk-1/KDR), FGFR1, or PDGFR (alpha and beta). Exemplary compositions have K_(i)'s of, for example, less than about 100 μM, less than about 10 μM, less than about 1 μM, and further for example having K_(i)'s of less than about 100 nM, and still further, for example, less than about 10 nM. The K_(i) for a compound is determined from the IC₅₀ based on three assumptions. First, only one compound molecule binds to the enzyme and there is no cooperativity. Second, the concentrations of active enzyme and the compound tested are known (i.e., there are no significant amounts of impurities or inactive forms in the preparations). Third, the enzymatic rate of the enzyme-inhibitor complex is zero. The rate (i.e., compound concentration) data are fitted to the equation: $V = {V_{\max}{E_{0}\left\lbrack {I - \frac{\left( {E_{0} + I_{0} + K_{d}} \right) - {\sqrt{\left( {E_{0} + I_{0} + K_{d}} \right)^{2} - {4E_{0}}}I_{0}}}{2E_{0}}} \right\rbrack}}$ where V is the observed rate, V_(max), is the rate of the free enzyme, I₀ is the inhibitor concentration, E₀ is the enzyme concentration, and K_(d) is the dissociation constant of the enzyme-inhibitor complex.

Another measure of inhibition is GI₅₀, defined as the concentration of the compound that results in a decrease in the rate of cell growth by fifty percent. Exemplary compounds have GI₅₀'s of, for example, less than about 1 mM, less than about 10 μM, less than about 1 μM, and further, for example, having GI₅₀'s of less than about 100 nM, still further having GI₅₀'s of less than about 10 nM. Measurement of GI₅₀ is done using a cell proliferation assay.

Tyrosine kinase activity is determined by 1) measurement of kinase-dependent ATP consumption by in the presence of a generic substrate such as, polyglutamic acid, tyrosine, 4:1 (pEY), by luciferase/luciferin-mediated chemiluminescence or; 2) incorporation of radioactive phosphate derived from ³³P-ATP into a generic substrate which has been adsorbed onto the well surface of polystyrene microtiter plates. Phosphorylated substrate products are quantified by scintillation spectrometry.

Kinase Specificity Assays:

Kinase activity and compound inhibition are investigated using one or more assay formats. The ATP concentrations for each assay are selected to be close to the Michaelis-Menten constant (K_(M)) for each individual kinase. Dose-response experiments are performed at 10 different inhibitor concentrations in a 384-well plate format. The data are fitted to the following four-parameter equation: Y=Min+(Max−Min)/(1+(X/IC ₅₀)ˆH) where Y is the observed signal, X is the inhibitor concentration, Min is the background signal in the absence of enzyme (0% enzyme activity), Max is the signal in the absence of inhibitor (100% enzyme activity), IC₅₀ is the inhibitor concentration at 50% enzyme inhibition and H represents the empirical Hill's slope to measure the cooperativity. Typically H is close to unity. Exemplary kinase assays are described below. KDR Assay

KDR biochemical activity was assessed using a Luciferase-Coupled Chemiluminescent Kinase assay (LCCA) format. Kinase activity was measured as the percent ATP remaining following the kinase reaction. Remaining ATP was detected by luciferase-luciferin-coupled chemiluminescence. Specifically, the reaction was initiated by mixing test compounds, 3 μM ATP, 1.6 μM poly-EY and 5 nM KDR (baculovirus expressed human KDR kinase domain D807-V1356) in a 20 uL assay buffer (20 mM Tris-HCL pH7.5, 10 mM MgCl₂, 0.01% Triton X-100, 1 mM DTT, 3 mM MnCl₂). The mixture is incubated at ambient temperature for 4 hours after which 20 uL luciferase-luciferin mix is added and the chemiluminescent signal read using a Wallac Victor² reader. The luciferase-luciferin mix consists of 50 mM HEPES, pH 7.8, 8.5 ug/mL oxalic acid (pH 7.8), 5 (or 50) mM DTT, 0.4% Triton X-100, 0.25 mg/niL coenzyme A, 63 uM AMP, 28 ug/mL luciferin and 40,000 units of light/mL luciferase.

c-Kit Assay

c-Kit biochemical activity was assessed using AlphaScreen™ (Perkin Elmer) technology, described above. Test compounds, ATP, biotinylated poly(Glu, Tyr) and c-Kit kinase were combined in a volume of 20 μL in a 384-well white, medium binding microtiter plate (Greiner). Reaction mixtures were incubated for 1 hr at ambient temperature. Reactions were quenched by addition of 10 uL of 15-30 mg/mL AlphaScreen bead suspension containing 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20. After 16 hr incubation at ambient temperature plates were read using an AlphaQuest reader (Perkin Elmer).
